PREPRUFE® 800PA Post-Applied Waterproofing Membrane

A high performance, fully-adhered, post-applied waterproofing system for critical below grade applications


The PREPRUFE® 800PA post-applied waterproofing membrane works with the PREPRUFE® pre-applied membranes to create a complete, fully integrated system for below-grade waterproofing.


The PREPRUFE® 800PA membrane helps contribute to methane, carbon dioxide and gas protection. Formulated to eliminate the use of known toxins, PREPRUFE® 800PA is free of any Red List materials or chemicals. 

    Specially formulated

    The non-asphaltic material was developed using PREPRUFE® membrane’s specially formulated synthetic adhesive. PREPRUFE® 800PA waterproofing aggressively adheres to substrates and to itself, creating a watertight bonded seal tested to withstand over 200 feet of hydrostatic pressure. This works to virtually eliminate any potential lateral water migration and to prevent water tracking between the membrane and the substrate. The PREPRUFE® 800PA product is also available in low temperature formulation, which provides application flexibility.

    Superior protection

    Utilizing a resilient, multi-layered film, the membrane provides superior protection against punctures. Its elastomeric properties accommodate minor structural movements and bridge concrete shrinkage cracks, reducing the risk of water intrusion and enhancing long-term structural durability. The 4-foot wide roll works to advance application efficiency, while significantly reducing the number of critical laps.
